1. Write a program that takes three numbers (a,b,c) from the user as input and finds the median of the three. The program has a method called median that takes 3 numbers as the parameter and returns the median. Use if-then-else statements to find the median. You can assume the three numbers are not the same. Sample Example: Enter 3 numbers 10 13 The median is 10 public class Median{ public static void main(String[] args){ Scanner input = new int a = int b = int c =
TASK 5. Methods Overloading. Review Methods, Implement the following code, test it with different input, make sure it runs without errors.

Besides main() this program has one method that computes the amount of raise and the new salary for an employee. The current salary and a performance rating (a String: "Excellent", "Good" or "Poor") are input. import java.util.Scanner; public class Salary { public static void main (String[] args) { Declare variables Prompt for and read current salary and rating For an excellent rating compute raise as 0.06 of current salary For a good rating compute raise as 0.04 of current salary For a poor rating compute raise as 0.015 of current salary You can use abc.equals(“xyz”) to verify the rating read For an invalid rating display an appropriate message and display the salary without change; otherwise, compute and print new salary and raise amount main() must display the message } } Note:- Please type and execute this java program and also need an output for this java program as soon as possible.
TASK 3. Console Input and Output. Review Scanner class and its methods, Implement the following code, make sure it runs without errors. 1 package 1lessons; 3 import java.util.Scanner; 4 5 public class ReportSum3 { public static void main(String args[]) { Scanner sc = new Scanner(System. in); 60 7 8 // Prompt the user to enter the first integer System.out.println("Enter the value for 'a' and press Enter: "); int a = sc.nextInt(); // Prompt the user to enter the second integer System.out.println("Enter the value for 'b' and press Enter: "); int b = sc.nextInt(); 10 11 12 13 14 15 16 17 18 19 20 21 22 } //Close the Scanner. It's a good practice to release the resource that was acquired sc.close(); // Display the result System.out.printf( "Provided Integers: %4d and %4d, the total is %5d\n", a, b, (a + b)); } To simplify the task, we came out with the idea to use Methods. Implement a method to add two integers.
Python Programming ONLY PLEASE NO JAVA Use recursion to determine the number of digits in an integer n. Hint: If n is < 10, it has one digit. Otherwise, it has one more digit than n / 10. Write the method and then write a test program to test the method Your test program must: Ask the user for a number Print the number of digits in that number. (describe the numbers printed to the console) Use program headers and method header comments in your code.
using System; class HelloWorld { static void Main() { int rows=21; int columns=76; for(int i=0;i<rows;i++) //for loop for printing the pattern for 21 rows { for(int j=1;j<=columns;j++) //for loop for printing the pattern in 76 columns { if((i+j)%7!=1 ) //if the addition of i and j does not give remainder of 1 when divided by 7 then Console.Write("-"); //print dash - on console else //otherwise peint a space on console Console.Write(" "); } Console.WriteLine(); //print a newline for printing on new row... } } }
